aexo values???

G'day all- was wondering if someone could help me by giving me their assessments of aexo values as the fpo's increase. Here is mine but it is really only a guess as I'm not entirely sure about how to do it,

aex- 5.7c
aexo- 4.3

aex- 6c
aexo- 4.5c

aex- 7c
aexo- 5c

aex- 8c
aexo- 5.5-6c

aex- 9c
aexo- 7c

aex-10c
aexo- 7.5c

As I said, these are just off the cuff as I am surprised at where the current aexo price is now let alone a bit further down the track.

Any input would be greatly appreciated
